create_tag

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations. Description only states action and optional nesting. Does not disclose behavior on duplicate names, error handling, or authentication needs. For a write operation, more detail expected.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with action and key optionality. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple create operation, but missing return value info and behavior on conflicts. With no output schema, description could clarify what is returned.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage 100%, so baseline 3. Description adds the 'optionally nested' context, which aligns with optional parameters but does not significantly extend beyond schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clear verb-resource pair: 'create a tag'. Specifies domain (OmniFocus) and optional nested under parent, distinguishing from sibling tools like list_tags or get_tasks_by_tag.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use or alternatives. Implicit from context of creating tags, but lacks guidance on when not to use (e.g., when tag exists) or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
